Seemingly, Dya is VERY quick on the draw this morning. He was posting his clear and concise response (see above) as I was typing out the stammer & stutter you see below!
My original pathetic fail of a response:
At some point in the past, you will have gone to visit an NPC, most likely in your ethnic home village location, who you asked to make the spell upgrade for you. This is a free service and will have been based upon your current quality level for that spell. This NPC has now finished that upgrade.
I believe this mechanic was recently disabled or upgraded and that you can now research your own spell upgrades but I am unsure how this new version works. Yours is most likely one of the spells that was in progress when they updated the mechanic and the system is cleaning up after itself...
